Lack of correlation between the prechallenge autologous nAb IC₅₀ titer and peak viral load or number of challenges required for infection. A Spearman analysis was performed using Prism 6.0 to determine whether the autologous nAb IC₅₀ titer for each vaccinated breakthrough monkey (n = 14) was correlated with (A) the peak plasma viral load (copies per mL) or (B) the number of SIVsmE660 intrarectal challenges required for infection. The nAb IC₅₀ titer is plotted along the x axis in both plots. In both cases, the correlation between the two parameters was not significant.
